5 Pcs SG90 Micro Servo Motor Mini Servo SG90 9g Servo Kit Compatible with RC Helicopter Airplane Car Boat Robot Arm/Hand/Walking/Servo Door Lock Control

works well

These motors are so good! I They work like they are suppose to, and they do consume some power. They are in the right price range, and normal noise level are provided. I think noise is a good way to check if they are working or not. I personally has to deal with power problems because I was using mac, but I figured it out!

The MG90S are really good i havent had any issues with it, i use them on my 3D printed helmets. but upon opening them up they turned out to be PLASTIC gears, with a METAL header. I thought these were ALL metal.

The servos work well as advertised and intended, although the screw heads aren't the same size. Sometimes it's Philips1 sometimes it's Phililps0, just keep that in mind and have those screwdrivers on hand.

Nice servo for building your own 3d printer bed level probe. It fit perfectly in the print found on instructables. I did have one go out on me and needed replaced, but that may have been from my experiments while building the probe and having the servo run past the hard stops on the probe. But you get 5 so there is room for error :)

All have continuous motion despite the spec saying 180. Very annoyed.

These work well for what they are. All 5 that I received were working.

The servos I had received are 90-degree servos, not the advertised 180-degree servos.Originally, all 5 servos worked. In the 2 years since I bought them, however, 2 servos have failed. This is likely my fault, however. When using them with a PCA9685, there was significant crosstalk before I figured out the issue. Specifically, one should place capacitors to eliminate noise on the power wires. My current setup uses 300 uF of capacitance and appears to eliminate all issues I had encountered with simultaneous control of the remaining working servos.
